Abstract
Electron spins in a semiconductor quantum well couple to an electric field via spin–orbit interaction. We show that the standard spin–orbit coupling mechanisms can provide extraordinarily efficient electron spin manipulation by an in-plane ac electric field.
Highlights
There is a growing understanding of the advantages of spin manipulation by a time-dependent electric field E (t) that couples to the electron spin through different mechanisms of spin–orbitSOinteraction.[3]
The coupling of twodimensional2Delectron spins to a perpendicular field E (t) develops due to a deviation from the strict 2D limit and is proportional to w/ ͑for w/Ӷ1), where w and are the confinement and magnetic lengths, respectively
We show that using an in-plane electric field E (t) results in a significant increase in the coupling of this field to electron spins
